Question 7

(3) types of RNA participate in protein synthesis

Answer 7

mRNA
tRNA
rRNA

Question 8

mRNA

Answer 8

Messanger RNA

Carries the recipe for making protein

Question 9

tRNA

Answer 9

Transfers the recipe

Question 10

rRNA

Answer 10

Ribosomal build the amino chain

Question 11

Condos

Answer 11

Sets of (3) nucleotides that code for specific amino acids

Question 12

Translation initiation

Answer 12

Begins when small ribosomal subunit binds to the beginning of mRNA

Question 13

Translation elongation

Answer 13

The next tRNA binds with the next codon

Question 14

Translation determination

Answer 14

Elongation continues until the ribosome encounters a stop condon

Question 15

The stop condons are:

Answer 15

UAA, UAG and UGA
